9.3. MANUAL CALIBRATION WITH ZERO/SPAN VALVES
There are a variety of valve options available on the GFC7001T/GFC7001TM for
handling calibration gases (see Table 1-1 for descriptions of each).
Generally performing calibration checks and zero/span point calibrations on analyzers
with these options installed is similar to the methods discussed in the previous sections
of this section. The primary differences are:
 On instruments with Z/S valve options, zero air and span gas is supplied to
the analyzer through other gas inlets besides the sample gas inlet.
 The zero and span calibration operations are initiated directly and
independently with dedicated buttons (CALZ & CALS).
9.3.1. SETUP FOR CALIBRATION USING VALVE OPTIONS
Each of the various calibration valve options requires a different pneumatic setup that is
dependent on the exact nature and number of valves present.
